2:24pm ET - Bomber Reportedly Tried to Enter Stade de France

According to a report from the Wall Street Journal, the attack on Stade de France was planned to resemble the deadly attacks at the Bataclan concert hall.

The paper spoke with a security guard who said the first blast heard at stadium was triggered by a suicide bomber who had a ticket to the game and was attempting to get inside. Security discovered the man's explosive vest during a routine pat down about 15 minutes into the match. The bomber detonated the vest shortly after he was denied entry into the stadium.

Police speculate that the plan was to detonate the vest inside the 80,000 capacity stadium "in order to provoke a deadly stampede." Read more about the incident on VICE Sports.

Paris prosecutor Francois Molins says authorities have identified seven of the assailants involved in the attacks, which were carried out by three teams of militants who all wore identical "push-button" suicide vests.

The prosecutor also said that 129 people have now been confirmed dead, with 352 injured and 99 in critical condition.

Molins said one of the men involved in the attack on the Bataclan concert hall was born in France. A different suicide attacker was identified by a Syrian passport that was found near his body at Stade de France. The Syrian man was not known to French intelligence services, the prosecutor said.

During the siege of the concert hall, where 89 people were killed, the attackers mentioned Syria and Iraq, Molins said.

The federal prosecutor's office in Belgium says authorities have so far made three arrests linked to the deadly attacks in Paris, according to the Associated Press. Molins said one of the men arrested in Belgium is a French national.

Jean-Pascal Thoreau, a spokesman for the Belgian prosecutor's office, said the arrests occurred near the border with France. Police were on the lookout for a rental car with Belgian plates that was seen near the Batalan theater. The man who rented the car was arrested, along with another individual. Both men were unknown to French security services, Molins said.

Belgian police also organized several raids in the Molenbeek neighborhood of Brussels on Saturday.
